  • Characterization of biochar surface functional groups

    Marija Ilić, Vesna Pavelkić, Aleksandar Lolić, Branko Leković (2021)
    In this work, biochar originating from paper fibres was examined. Biochar was prepared via pyrolysis method at 550°C. Oxygen-containing functional groups on biochar surface were determined. The surface functional groups of biochar were analysed by Fourier transform infrared spectroscopy. The amount of oxygen-containing functional groups was performed with Boehm titration. The total acidity of biochar was mostly attributed to carboxylic and lactonic groups.

    Jelena Ćalić, Dejan Jeremić, Ana Mladenović (2023.)
    The year 2014 was the year of extremely large floods in Serbia. The territories of municipalities Kladovo and Negotin, along the Danube course in Eastern Serbia, were among the worst affected, mostly by flash floods. The karst ridge of Dževrinska Greda, a typical contact karst and stripe karst environment formed within Upper Jurassic limestones, suffered significant morphological changes in terms of heavy washout of sediments on one hand (in fluviokarstic gorges and active cave passages), and on the other ...

    Katarina Urošević, Jelena Zakonović, Radmila Gaćina (2019)
    Mining is a global industry that is of great importance for every product which is used by human. For mining, process efficiency, reducing production downtime, increasing profitability are all very important. Soft computing tehnologies (SC) are helping in the process of transforming the mining industry into a safer and more environmental friendly industry, but keeping in mind the financial aspect as well. In this paper some of fields of blasting activities in which the SC methods have been applicated, ...

  • Microemulsion with aromatic oil as cleaner media for electropolymerisation

    M. Ilić, F.-H. Haegel, S. Zlatanovic, N. Potkonjak, B. Simonovic (2005)
    Abstract Microemulsion polymerization is widely used as a cleaner alternative way to prepare intrinsically conductive polymers. We studied isothermal phase diagrams for microemulsions of the electropolymerizable heterocyclic aromatic oil 3,4-ethylenedioxythiophene (EDOT), aqueous LiClO4 solution and alkyl polyethoxylate. Our specific goal was to assess the effect of LiClO4 salt on the phase behaviour. The phase behaviour was characterized by stepwise titration and microscopic analyses. Here we found that the increase of the concentration of LiClO4 salt shifts the microemulsion region ...

  • Defining structural correlation using of total horizontal gradient

    Snežana Ignjatović, Ivana Vasiljević, Milanka Negovanović (2021)
    Gravity data can help to define the structural correlation along significant vertical shifts. The different procedures of mathematical transformations on gravity data are applied to define structural correlations. The paper presents the results obtained using the procedure total horizontal gradient on gravity data. The application of the total horizontal gradient helped to detect contacts with a large dip angle (vertical or subvertical contacts), which can be interpreted as faults. The study area located in the wider area of the ...

  • Temperature induced evolution of nanostructured Ni0.9Zn0.1O

    Kremenović Aleksandar, Antić Bratislav, Vučinić-Vasić Milica, Colomban Philippe, Jovalekić Čedomir, Bibić Nataša, Kahlenberg Volker, Leoni Matteo (2010)
    The crystal structure and microstructure of as-prepared and annealed Ni0.9Zn0.1O were refined at room temperature in both the Fm (3) over barm and R (3) over barm space groups. It is shown that below the Neel point (458 K), where magnetic ordering triggers the presence of a trigonal strain, the common usage of a higher-symmetry non-admissible space group for crystal structure and microstructure analysis via the Rietveld method may result in both an incorrect structure description and incorrect microstructure ...

  • A methodology for assessing the pressures on transboundary groundwater quantity and quality – experiences from the Dinaric karst

    Zoran Stevanović, Veljko Marinović (2020)
    A relatively novel and abridged methodology for assessing the quantity and quality status of groundwater bodies has been applied in the Dinaric karst of SE Europe. Validation of pressure on quantity is based on groundwater budgeting and the correlation of available groundwater reserves and projected water demands, while pressure on quality is estimated by GIS-created maps: vulnerability – hazard – risk. The results obtained from the studied groundwater bodies indicate mostly low pressure on water quantity, but increased risk from diffuse and point pollution sources. ...
